Abstract: We report calculated cross sections for the electronic excitation of carbon monoxide by positron impact. The calculations were carried out with the Schwinger multichannel method and included six collision channels, namely the ground (X1Σ+) and five electronically excited (A 1 II, I 1Σ−and D1Δ) states. Present calculated excitation cross sections to the A1II state did not present any resonant features, being in this sense consistent with previous calculations for the isoelectronic nitrogen molecule. The experimental a1IIg excitation cross section of N2 presented a resonantlike structure which would also be expected in the A1II excitation of CO. We discuss possible reasons for the disagreement between experiment and theory.
